自动升级php代码[关闭]

Question

I have found this tool that downgrade the php code from php5.4 to 5.3 https://github.com/endel/php-code-downgrade

actually do you know if there's something to upgrade from 5.3 to 5.4? because my php code seems not to work anymore and it was in php5.3 that is no more support by my webhost

edit: I solved at the end.. I just found out that the problem was a server configuration of the web-hosting :) (#FCGI mode)

Answer 1

PHP 5.4 is backward compatible with 5.3. If anything you should just be seeing notices in your error logs. Turn on error reporting E_ALL and check your logs for any issues. For a list of features deprecated between 5.3 and 5.4 check PHP 5.4 Deprecated Features.
